Notes:

The four expression types that can be handled by the compiler are _Real (machine real numbers), _Integer (machine integers), _Complex (complex numbers with machine real components), and True|False (boolean expressions).

In Mathematica Version 3.0, the compiler can also handle arrays of elements, provided all of the elements are of the same type.

The part of Mathematica that handles evaluation of CompiledFunction expressions is called the CompiledFunction interpreter. Compiled evaluation refers to evaluation that is handled within the CompiledFunction interpreter. Compiled evaluation will normally be more efficient than uncompiled evaluation.

The following table gives the functions that are handled within the CompiledFunction interpreter in Version 3.0 of Mathematica. With few exceptions (such as Function, which is handled in a special way), computations involving functions that are not on this list are handled by calling uncompiled evaluation.
